Typo on the Halloween contest Answered
On https://www.instructables.com/contest/halloween2012epiccostumes/?show=PRIZES The prizes page of the current halloween contest, there is a typo:
Two Grand Prize winners selected from all 6 categories will be awarded their choice of a 5-inch 2.6 GHz Retina display MacBook Pro OR a Full Spectrum 40W Laser New Hobby Laser Cutter with a 20”x12” cutting bed. Winners will also receive an Instructables Prize Pack.
I believe that should be 15 inch :)
